Detailed description of the invention
Fig. 1 is the process flow diagram of the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation and the invention is not limited to following embodiments.
Embodiment.
Referring to Fig. 1, the present embodiment rotor is from powder metallurgy to cold extruding formation process, and steps are as follows:
(1) material: being first heat-treated by cold extrusion forming, then carries out phosphorus saponification process, and material is then carried out cold extrusion forming.
(2) smart car large cylindrical: large cylindrical smart car is formed by machining.
(3) the small outer diameter of smart car: small external diameter lathe finish is formed by machining.
(4) it mills flat recess: positioning flat recess angle by the small outer diameter of fixation, by cross recess, carry out flat recess processing.
(5) cross recess is milled: by fixed large cylindrical, by, come the positioning cross angle of the v-groove, carrying out finish-milling on the basis of flat recess
Cross recess and brill aperture.
(6) modifier treatment.
The present embodiment Product Process so that 4-5 grades of material structure nodulizing grade, is conducive to material flowability by heat treatment,
Carry out again phosphorus saponification process make material surface have phosphate coating and saponification layer, can reduce frictional force, material carry out cold-extruded at
